new and useful Improvements in Textile Twisting Machines, of which the following is a-speciiication.

Y This invention relates to improvements 1n strand-twisting machines, that is, machines of the class arranged to lay and twist a plurality of independent threads so as to produce a laid cable.

In a multiple strand twisting-machine provided with my improvements, each spoolcarrying spindle thereof is constructed and arranged to term a selfcontained, self-lubrleating unit, in which the revoluble spindle or blade proper is flexibly mounted. In a twisting-machineof this general type and having my improvements, the blade, bolster, and holster-casing are more thoroughly protected and may be readily and accurately mounted and demounted at will; the bolster member is submerged in oil or other suitable lubricant, thereby permittin the spindle to run at an increased rate 0 speed without throwing or scattering the oil about and injuring the spools and strands. Obviously, a

twisting-machine possessing these advantages is capable of materially increasing its output without increasing the cost of attend' ant labor.

In the accompanyingdrawlngs, Figure 1 is atransverse sectional view, in partial elevation, the portion of the machine represented being-at the left of the center line 7 'w-w; Fig. 2 is a sectional view, taken substantially on the vertical center line 22 of Fig. 1, showing, in enlarged scale, the manner of constructing and mounting the spindle, spindle-holster,and its support; Fig. 3

is a partial plan view of the spool-hplder or cage, the spool being omitted from this view; and Fig. 4 is a plan, partly in section, taken substantially on line 44-of Fig.1, showing the arrangement of a grou of the spindle units and the manner of driving them by means of gearing.

Textile twisting or cable-producin machines ot the general type illustrated in the drawings are usually provided with co-operable lower and upper series of inde ndent twisting-head units, termed first an second twist, respectively.

first twist units is arranged to twist the individual threads or strands singly of a plurality of grouped, independently mounted spools carrying the thread, while at the same t me each ofthe upper or second-twist units is caused to twist together into a single cord or cable the twisted individual strands drawn from the corresponding group ofunits may be arranged longitudinally of the machine in two parallel rows and spaced apart at equal distances in the rowsand driven by mechanism capable of actuating the several heads simultaneously.

The main supporting frame of the chine is omitted from the drawing; the upper and lower ties t, t and the lower crossplate t are, however, represented cross-sectionally; these tie members extendlon itudinally along the side of the machine an are adapted to support the twisting-head units at suitable intervals. twisting-head units consists essentially of a plurality of supported stationar tubular bolster-cases a (three being shownl each of the bolster-cases has its upper portion a loosely fitting a recess b formed in the underside of the annular neck I) of the respeccentral verticalrotary spindleblade 8, having its upper portion 8 ada ted to receive a spool b, carrying a stran or thread p,- the lower portion 8 of the s indieb a non-revoluble bolster C, removably mourited in its corresponding holster-case a, which in turn is removab'ly sup orted in the lower cross-plate or rail cc also Fig. 1.

Formed integral with the bolster-case a is an oil receptacle G which communicates with said bolster-case by means of the channel 9. The bolster C is provided with an opening g adjacent the inner end of channel g, to permit the oil to pass into said bolster C and lubricate blades, as shown in Fig. 2.'

The .outer peripheral edge oflthe baseplate 5 of the cage is provided with a series of spaced-upright pins b fixed at the top to the ring member b, the latter having a plurality of threading-eyes b therethrough alternating with the pins. These .pins and Each of the lower.

The spindle-blade and cage members are adapted to be positively rotated by means of a small gear (1 fixed to the annular neck 6 of the cage or base-plate; said gear at being actuated by a transmission gear d,.

The twisting element D and frame h are adapted to revolve in unison in one direction through the medium of a main drivingshaft 011*, gears 0, 0 and 0 while the haulerrolls are actuated in the same direction by a shaft m and gears m mi m, etc., ina well-known way. The reel F, or other analogous windin means, is adapted to wind the finished ca 1e or cord thereon under considerable tension.

It is deemed unnecessary to include herewith a more detailed description of the machine and the manner of operation, since the general construction and action of twisting-machines are well known. My invention resides more specifically in certain novel features of construction which render the machine more eflicient, in that the speed may be materially increased, thereby increasing the product or output; the spindles are more accurately mounted and are operated with less power, while the spindle and bolster members are capable of being more readily of a disk therefrom at will, as desired.

I claim' as my invention:

'mounted in their supports and withdrawn and a cage secured to said spindle, said cage comprising a circular base-plate a series of peripherally arranged upright pins secured thereto and a ring-member secured to the top of said pins and provided with a series of threading eyes.

2. A -twisting machine having combination a bolster-case, combined bolster and step bearings mounted in said bolster-case, an up-twist spindle mounted in said bearings, a cage secured to said spindle and provided with a downwardly extending neckportion provided with a recess adapted to receive the upper portion of said bolstercase.

3. A twisting-machine having "in combination a bolster-case, combined bolster and step bearings mounted in said bolster-case, an up-twist spindle mounted in said bearings, a cage secured to said spindle and provided with a downwardly extending neckportion provided with a recess to receive the upperend of saidbolster-case and with an external driving gear uponthe free-end of.

said neck-portion.

4. A twistlng machine havmg 1n combination a cross-plate, a bolster-case secured in said cross-plate, combined bolster and step bearings mounted in said bolster-case, an

up-twist spindle mounted in said bearings,

a cage secured to said spindle and provided with a downwardly extending tubular neck portion adapted to receive the upper end of said bolster-case, and a driving'gear formed integral with said tubular neck-portion and having its transverse axis located approximately midway between the-top of the cross-plate and the top of the bolstercase.

In testimony whereof I have affixed my signature in presence of two witnesses.
